FU'MIGATOR.

Specification of Letters Patent.

Patented Nov. 3, 1908.

Application filed July 7, 1908. Serial No. 442,345.

T all whom it may concern:

Be it known that I, DANIEL F. FoL'rz, a citizen of the United States, residing at Calumet, in the county of Canadian and State of Oklahoma, have invented certain new and useful lmprovements in Fumigators, of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to improvements in fumigators and consists of the novel features of construction and the combination and arrangement of parts hereinafter fully described and claimed.

The object of the invention is to provide a simple, practical and handy fuinigating device which may be effectively used for killing mite, boll weevil, and the like in grain or other seed and also for exterminating rats and other small animals.

The above and other objects of the invention are attained in its preferred embodiment illustrated in the accompanying drawings, in which Figure 1 is a perspective view of my improved fumigator; Fig. 2 is an enlarged vertical longitudinal section; and Fig. 3 is a vertical transverse section.

My improved fumigator comprises a body 1 preferably of rectangular form having arranged within it a transverse partition 2 to divide it into a fire box or chamber 3 and a smoke or fume chamber 4. 1n the partition 2 is a large opening 5 closed by a hinged valve 0 which is actuated to its closed positionby a spring 7. Projecting through the front end of the body is a smoke or fume discharge pipe 8 the inner end of which has a funnel-shaped enlargement 9 and the outer end of which is turned upwardly and secured by a clamp 10 to the top of the box. This upturned outer end of the pipe 8 is connected to a cross pipe having one branch 11 extending inwardly and connected by a coupling 12 to a cylinder 13 of a force pump and its other branch 14 extending outwardly and adapted to receive a flexible pipe or hose 15 or any other suitable discharge pipe or noz- Zle. The cylinder of the pump is arranged longitudinally above the center of the body 1 and is supported above the same by brackets 16 so that said cylinder may be used as a handle for the body. The piston 17 within the pump cylinder is secured to the inner end of the piston rod 18, the outer end of which is provided with a suitable handle 19. Ar-

ranged within the pipe 14 is a check valve 20 preferably in the form of a ball valve so arranged that when the piston 17 is drawn rearwardly said pipe 14 will be closed so that the smoke and fumes in the chambers 3, 4 will be drawn into the pump cylinder, the valve 6 being opened by the suction in the chamber 4; and when said piston 17 is forced outwardly the valve 6 closes and the valve 20 opens so that the smoke and fumes will be discharged from the hose or nozzle 15.

Within the chamber 3 at the rear end of the body is a removable fire box or grate 21 in which charcoal, chips of wood or other fuel may be burned so that when sulfur or any other chemicals or drugs are thrown upon the fire the smoke and fumes from the same will fill the body and be drawn from the latter by the pump. The fire box 2 is here shown in the form of a sliding drawer having on its outer end a handle 22 and a suitable fastening 23.

In order to permit oil to be used as the fuel and to permit a liquid fumigating or disinfecting compound to be used to produce the smoke or fumes, I preferably make the rear end 24 of the body in the form of a hinged'door which may be opened to permit a lamp 25 to be set in the fire box or grate 21. This lamp has supported above its burner a receptacle 26 for either liquid or solid substance which when heated or burned will produce fumes or vapors. The door 24 may be provided with a suitable fastener 27.

From the foregoing it will be seen that the invention may be used for fumigating, disinfecting and analogous purposes. By boring small holes in the lower portion of a grain bin or the like and inserting the tube 15 therein, fumes may be forced through the grain or seed to kill mite, insects and parasites. When the tube 15 is inserted in a rat hole or the hole made by any burrowing animal, fumes may be forced into such hole to kill or drive out the animals therein. It will be noted that the device is simple in construction so that it may be produced at a comparatively small cost and will be strong and durable. It is also inexpensive to operate and convenient to handle.

Having thus described my invention what I claim is:

A device of the character described comprising a body, a partition therein dividing it into two chambers and formed with an opening, a valve to close said opening, a

removable fire box in one of said chambers, In testimony whereof I hereunto afiiX my a discharge pipe leading from the other signature in the presence of two Witnesses. chaniber and having two branches, a check DANIEL F- FOLTZ valve in one of said branches, and a puinp 5 having its cylinder connected to the other Witnessesi branch of said pipe and spaced from the A. M; CARNAHAN,

top of the body to provide a handle. VIOLA REYNOLDS.
